Description:
GGD Type Low voltage fixed switchgear is applicable to distribution system of AC 50Hz, rated working voltage of 380V and used to power conversion, distribution and control for power, lighting and distribution equipment.
The switchgear meets the standards IEC60439-1 and GB7251, etc.
Features:
u The form of a universal cabinet, the frame which is assembled by partial welding of 8MF cold-formed steel and matching supply of fixed-point manufacturers guarantee the accuracy and quality of the cabinet.
u Modular design of components shortens manufacturing cycle and increases work efficiency.
u The unique design of the heat sink slot allows the sealed cabinet to form a natural air duct for heat dissipation.
u The golden section design makes the overall appearance beautiful and generous.
u The hinged hinge of the door and the special design of the rubber strip improve the IP grade.
u Connection design between instrument door and cabinet mounting and frame forms complete ground protection circuit.
u The top cover of the cabinet can be removed if needed. The lifting ring on the top is easy to lift and ship.
